[Mutt] #2903: check PGP signature in background
#2903: check PGP signature in background
Mutt should have an option to be able to check the PGP signature in
background, as retrieving the key often takes time. Once the signature is
checked, the index line should automatically be updated. The pager could
also be automatically updated, but in this case, Mutt should make sure
that it doesn't cause scrolling (except when the top of the message is
displayed).
